:oncaruaomzmt ATTAcHMEN ron ENGINES.

To all whom it may concern lie-it known that I, GRANT MoNnEL, a citizen of the United States, residing at North Platte, in the county of Lincoln, State of Nebraska, have invented a new and useful Decarbonizer Attachment for Engines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a decarbonizing and fuel saving attachment for internal combustion engines, and has for its object to provide a device of thischaracter which embodies novel feature of construction whereby a fine spray of warm water is delivered into the born or intake of the carbureter when the engine is running at high speeds, thereby obtaining a moist mixture which will give increased power to the engine and keep the cylinder heads and valve chambers clear of carbon deposits.

Further objects of the invention are to provide an attachment of this character which can be readily applied to any conventional water cooled internal combustion engrim, and which isautomatically governed T in its action by the throttle control lever so that there is no moistitre applied to the carbureter when the engine is running at low speeds, although the su ply of water automatically starts when t e throttle is opened a predetermined amount and a increases as the throttle is still further opened to s eed up the engine. I w

ith these and other objects in view, the

invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the descriptioripro ceeds, the nove features thereof being pointed out in the ap )ended claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Y Figure 1 is a side elevation of an automobile engine provided with a fuel saving and decarbonizing attachment constructed in accordance with the invention. Fig. 2 is an enlarged top plan view of the attachment, portions being broken away and shown in section.

Fig. 3 is a detail view showing the manner of applyin the nozzle to a carbureter having a close air intake orhorn.

a manifold 1 which leads from a conventional carbureter 2. A throttle valve 3 is arranged in the manifold 1 for controlling the supply of the explosive mixture to the engine in the usual manner, said throttle valve being provided with a crank arm 4 which is operatively connected in some suitable manner as by means of a link 5 to a throttle control lever 6. This is all of the conventional construction, and no claim to novelty isbased thereon.

In carrying out the invention an opening is drilled in the water jacket of the engine A and the threaded end 7 of a tubular plug 7 screwed into the opening so that the plug is in communication with the water jacket. 'lhis plug is provided at an intermediate point in its length with a cut out valve 8 A finger piece 10 is applied to the cut out valve and provides a convenient means for manually opening and closing the same, while the control valve is provided with a crank arm 11 which is operatively connected to the throttle control lever 6 so that the control valve remains closed until after the throttle valve has been opened a sufficient amount for the engine to obtain a comparatively high speed. Any suitable means such as a spring 12 may be provided for normall holding the control valve in a closed cs1- .tion and causing it to return to a cosed position as soon as it is released by the mechanism for opening the same. A cap 13 is fitted upon t eouter end of the tubular plug 7, said cap being formed with a comparatively small lateral arm 13 to which one end ofa small water conduit 14 is connected by a suitable coupling 15.

A laterally projecting nozzle 16 is ap plied to the opposite end of the water conduit 14, said nozzle being adapted to enter l I; the air horn or intake 20-of the carbureter,

and being provided with a needle valve 17 which controls the flow of water through the same. Means is preferably provided for clamping the nozzle 16 in operative position upon the air intake of the carbureter, and

for this purpose the head of the nozzle may be formed upon one side with an ear 16 'havin pivot pins 18 projecting laterally there rom. A split clamping collar 1.9

- has-the back thereof ivotally mounted upon the pins 18 so that t e collar can be swung into a position at right angles to-the body of the nozzle or into a position parallel with :the body ofthe nozzle. When the air horn or intake of the carbureter is open ended,

. as indicated at'2" on Fig. 2, the nozzle 16 is arranged to project into the open end of the air horn and the clamping collar 19 rotated into the position parallel to the body of the nozzle 'so that it can be-fitted around the air born. The arms of the split clamping collar ma be formed in telescoping sections, if desire ,so that the clamping collar can be made larger or smaller, and the free ends can be fitted around the air intake and fastened in position thereon.

The connection between the control valve 9 of the attachment and the throttle control lever 6 includes a rod 21 which has one end thereof secured to the crank arm 11 of the control valve, while the opposite end thereof is provided with an adjustable set collar 22 and is slidably received within guides 23 upon a rod 24 which is connected to the throttle control lever 6. The adjustment is.

such that when the throttle valve6- is only slightly opened andithe engine is running at ow speedthe guides 23 of the short rod 24 do not engage the set collar 22 and the rod 21, is not moved to open the control when the throttle valve valve 9. However d'a sufiicient amount for 3 has been opene the engine to obtain predetermined speed,

the'guides 23 engage e set collar 22 sothat a further opening of the throttle valve is accompanie .by ,an opening of the control a valve 9. Warm water from the water jacket of the engine will flow through the tubular plug 7 and water conduit 14 so as to be sprayed into the air intake of the carburetor when the control valve 9 is opened. When the engine is running slowly and. requires a rich mixture the control valve 9 remains closed, so that no water enters the-carbureter, although when the throttle ':valve is opened a sufficient amount for the engine to speed up the control valve is opened. The

amount of water supplied to the carbureter and entering into the mixture thus increases as the throttle is opened to speediup the engine, although the supply of water is en'- tirely cut off when the engine is running at low speeds. The ordinary gas and air' mixture is too dry for complete combustion, and as en ne speeds increase moie'moisture 1s require to give the best results. The attachment works automatically and re uires 7 no attention after being installed an adjusted. The use of the attachment not only enables greater power to be obtained from the engine owing to the fact that a better mixture is furmshed at high speeds, but resultsin a thorou h cleaning of a carbonized motor and t e prevention of subsequent carbon deposits inthe cylinder heads or valve chambers.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

ternal combustion engi e, including its carbureter and throttle valve, of a water 0011-: duit leadin' from the water jacket of the engine to the air intake of the carbureter,

a control valve for the conduit a throttle control lever, a pair of rods slidably engaging each other and o ratively connected to the control valve an throttle controllever, respectively, stop means for limiting the sliding movements of the 'rods and causin the control valve to open after the throttle lever has been moved a predetermined amount, and a rod connecting the throttle control lever to the throttle, the sto means associated with the pair of slida 1e rods being arra d 50 that the control valve is not move until after the throttle valve has been opened a redetermined amount.
